Calibration & Pump Priming

If more than the required volume of chemical is obtained, adjust the speed control knob to a lower setting and rerun the calibration check. Continue this operation until the proper rates are being measured.

When you’ve obtained the proper chemical-to-seed ratio, reconnect the discharge line to the fitting on the application tube. You are ready to treat seed when the proper chemical-to-seed rates are obtained. The chemical will be applied to the seed in the transition. The seed and chemical will be mixed in the blending chamber. Treated seed will then be discharged through the two-way bagger. Be sure a bag or seed bin is below the bagger to catch the treated seed when your treating operation begins.

1.Turn on the power switch for the blending chamber drum.

2.Turn on the chemical applicator power switch.

3.When chemical begins flowing, immediately open the seed gate.

Treating will begin.

4.As soon as seed flow stops, turn off the chemical aplicator switch. The chemical “does not” stop automatically. You must turn off the pump switch yo stop the chemical flow.

Routine calibration should be monitored to ensure the integrity of chemical application rates. Compare the number of seed units treated with the total amount of chemical used to determine if correct rates are obtained. Readjust chemical flow accordingly.

Since your seed may be slightly moist after treating, it will probably be necessary to open your drill more than usual to ensure proper seeding rates (usually at least 10% over untreated seed). Treated seed gener- ally does not flow as freely as untreated seed.

Check your calibration. If extremely high or low temperatures

exist, the viscosity and flowability of certain treatment chemicals will change. A typical example - treating early in the morning at cooler temperatures and then in the afternoon with warmer temps.
